PANAMA CITY BEACH, Fla. — Back in custody after using forged documents to escape their life sentences, two convicted killers were being grilled on Sunday by law enforcement authorities who said they expect to make more arrests in a case that has given both court and corrections officials in Florida a black eye.

Among the questions being posed to Joseph Jenkins and Charles Walker: Who forged the papers? Who helped you run from police? What other prisoners have gotten away with this? Who was coming from Atlanta to whisk you out of Florida?
